GLP-1 / Metabolic

Retatrutide + Cagrilintide

Also known as: Reta + Cagri, Triple-agonist + amylin blend

Research use only · not FDA-approved

Pre-mixed metabolic blend combining retatrutide, an investigational GIP/GLP-1/glucagon triple receptor agonist, with cagrilintide, a long-acting amylin analog, both targeting appetite, satiety and energy balance for weight loss. Neither component is FDA-approved: retatrutide is in Eli Lilly's Phase 3 TRIUMPH program (NDA anticipated late 2026, approval not expected before 2027), and cagrilintide is investigational, studied mainly in Novo Nordisk's CagriSema combination. This specific blend is not an approved product and has no published controlled human efficacy or safety data; any rationale is inferred from the separate development-stage compounds, and combination-specific human data is lacking.

About Retatrutide + Cagrilintide

CAS

Molecular formula

Typical dose range

No validated or approved blend protocol exists. Investigational/vendor ranges for the components: retatrutide titrated from ~2 mg up toward 8–12 mg once weekly subcutaneous in trials; cagrilintide ~0.3–2.4 mg once weekly subcutaneous. Research use only — doses are not clinically established for the mixture.

Half-life

Component-dependent and not characterized for the mixture. Both retatrutide and cagrilintide are engineered for once-weekly dosing, consistent with multi-day plasma half-lives.

Common research uses

Marketed (research only) for weight loss and obesity-related metabolic supportClaimed appetite suppression and improved satietyInvestigational/research interest in additive metabolic effects of incretin + amylin pathways

Safety notes

Not FDA-approved in any form; sold as a research/grey-market compound while both components remain investigational. No combination-specific human safety data. Known incretin- and amylin-class risks include nausea, vomiting and other GI effects, with retatrutide's glucagon agonism raising additional questions around heart rate and glucose handling under ongoing study. Stacking two appetite-suppressing agents may amplify GI and nutritional risks.

Reconstitution

Often supplied lyophilized; reconstitute with bacteriostatic water and refrigerate. As an unapproved investigational-peptide blend, dose accuracy, sterility and content of the combined compounds are not assured.
